EASE-UP MOTION FOR THE TENSION-FALLERS OF SPINNING-MULES.

Specification of Letters Patent.

Application filed April 17, 1918. Serial No. 229,068.

To all whom it may concern:

Be it lmown that I, JAMES DAVIDSON, of the city of Toronto, in thecounty of York and Province of Ontario, Dominion of Canada, haveinvented certain new and useful Improvements in Ease-Up Motions for theTension-Fallers of Spinning-Mules; and I hereby declare that thefollowing is a full, clear, and exact description ofthe same. 77

This invention relates to an ease-up motion for the tension mechanism ofa spinning mule, the object of the invention being to construct andarrange the sliding incline that it will so control the descent of theease up shoe and tension weights during the backing oif motion of the sinning mule, as to prevent the breaking o the yarn, as hereinafterdescribed and particularly pointed out in the claims.

For an understanding of the invention, reference is to be had to thefollowing description and to the accompanying drawings, in which Figure1, is a fragmentary rear elevational view showing the guide and tensionshafts,

and their respective fallers, and related parts, in the neutralposition; 7

Fig. 2, is a sectional elevational view on the line wa, Fig. 1, showingthe same part-s in full lines in the neutral position, and in dottedlines in the backing ofl' position;

Fig. 3, is a side elevational view of the sliding incline for theease-up shoe of the tension mechanism, showing it at the limit of itsin-movement; V

Fig. 4, is a rear elevational view of the parts shown in Fig. 3; A

Fig.- 5, is a detail sectlonal elevational view on th line b- Fig. 1, ofthe guide and tension fallers, the ease-up shoe, and the connecting rodand lever for the tension fallerrock shaft, in the neutral position, andthe sliding incline engaged by the ease-up shoe; and, v

Fig. 6, is a similar view to Fig. 5, showing the 'tion of the same partswhen the mule is acked 011. 4 p

a represents the carriage; b represents an arm secured to thecarriage; 0represents the guide-fallershaft, and d represents the tension fallershaft, both of which are journaled in the arm b. Fixed on the guidefaller shaft 0 is the guide faller e, and fixed on the tension fallershaft (1, is the tension faller f.-

Encircling the guide and tension faller shafts 0 and d, is a casting 9,formed with a toothed segment'h, partly surrounding the guide fallershaft 0. Encircling the guide faller shaft 0, is a casting i, to whichis connected the faller lock 9', formed with a toothed segment is,meshing with the toothed segment h. Fixed on the tension faller shaft d,is an arm Z, having at its outer end a grooved segment m, to which isconnected the chain 0, and suspended from the chain 0, are the tensionweights 1? and brace Q, the brace being below the tension weights.Connecting the faller lock j with the brace g, is a chain 8 and wire t,to uphold the brace and tension weights when the guide and tensionfallers are in their neutral position.- Secured to the guide fallershaft 0, is a leather strap u, and attached to the strap a, is the 7guide faller spring '0, the lower end of the:

spring '0 being attached to a casting to at the lower end of the arm I).The tension faller shaft d is provided with a lever d, to which ispivotally connected arod e, attached at its lower end to an ease-up shoef, which rides on the sliding incline when thespinning mule is in thebacking-0E position.

With the exception of the sliding incline,

the above enumerated parts are similar to 7 those in general use onspinning mules of the Johnson and Bassett, or Davis and Furbur types.

The slidi inoline,'however, is essentially different in 1ts structuralcharacter, opera- 7 tion, and purpose, from any other incline which hasbeen previously employed in connection with the tension mechanism, and,as shown in the drawings, consists of a stationary slide-way a, arrangedlengthwise of the in and out run of the carriage, and approximately atthe limit of the outrun. Movable in the slideway a, is a. block b havinan elongated vertical groove or slot 0'. nnected to the block b,and tothe slideway a, is a spring or springs d, to resist the movement of theblock in the direction of the out run of the carriage, and to cause themovement of the blockin the direction of the in run of the carriage,when niovthe purpose of the adjustment being to cor reotly regulate themovement of the sliding incline to the backing ofl' motion of the mule.

Carried by the block 6, is the incline 7', provided with a vertical arm5/ engaging the side of the block b, and passing through the arm 5/ andthrough the groove or slot is a clamping bolt it by which the incline issecured to the block.

By means of the arm g, clamping bolt it, and groove or slot 0', the apexof the incline can be adjusted to any predetermined height within therange of the groove or slot 0 to compensate for variations in the levelof the loor.

Depending from the underside of the in cline f, near its lower end, is alug 2', which engages the stop 6 to arrest the forward movement of theblock and the incline during the inrun of the sliding incline with thecarriage.

During the outrun of the carriage, the ease-up shoe f7 engages theincline 7" and moves it in the direction of the outrun of the carriageto the limit of movement, the spring or springs cl maintaining theincline constantly in contact with the ease-up shoe.

During the outrun of the carriage, the guide and tension fallers, andtheir related parts, including the ease-up shoe, are in their neutralposition, as shown in Fig. 5 of the drawings, and in this position, theease-up shoe is engaging the incline near its apex.

When the mule backs off, the guide and tension fallers, the fa-llerlock, and the easeup shoe and tension weights, move from the positionshown in full lines in Fig. 2, to that shown in dotted lines in the samefigure, and during this movement, the ease-up shoe pushes the slidingincline in an outrun direction, as indicated by arrow in F ig. 5, beforethe spinning mule starts its inrun.

lVhen the mule has started its inrun, the sliding incline moves inwardlywith it until the lug 2" engages the stop 6' and arrests its continuedmovement in an inward direct-ion.

By maintaining the sliding incline in contact with the ease-up shoeduring the backing ofi movement, and arranging the sliding incline sothat it will move in the direction of the outrun of the carriage duringthe descent of the ease-up shoe. it is possible to so control thebacking off of the spinning mule as to prevent any sudden or irreg ularmovement of the tension fallers.v and thus overcome the tendency of thetension fallers to break the yarn through the sud den application of thetension; which is the essential purpose o-f'the inventions An advantagearising from the use of the sliding incline, is the ability to'a-pplygreater weight to the tension fallers than was possible by the use ofthe stationary incline, and this increased weight enables the spinningmuleto wind the yarntightly on the bobbins,

and thereby materially increase the quantity of ya rn to the set.

Having thus fully described the nature of my invention, what I claim asnew and desire to secure by Letters Patent, is

1, In a spinning mule, the combination with the carriage, the tensionshaft and faller, and the tension means for thetension shaft, of anease-up motion for the ten sion shaft, comprising a shoe connected withthe tension shaft, a sliding support engaged by and movable with theshoe during the outrun of the carriage, and selfunovable with the shoeduring a portion of the inrun of the carriage.
